Hello, my dad was diagnosed with lung cancer 2022 right lung, had surgery successfully then his left lung had cancerous cells 2024 and had radiotherapy that treated it successfully. However this year gone in Nov 2025 he found out he had a 5cm large mass in his right brain believed to have spread from the lungs. He had surgery 2nd Dec and consultant says it went well and majority of the mass has been removed. We haven’t had a lot of info given but he is now waiting for targeted radiotherapy as the gap is too large for him to have radiotherapy initially at the first hospital and they believe there is more risk and to have targetted radiotherapy as a better/safe way to treat.
He has been on dexamethasone for 2 months or so and had pretty good stability, overall not too bad health, mainly breathlessness and mild forgetfulness. We had MRI results back after he had that done prior to radiotherapy planning and they have said he has some progression of cancer still. Realistically, what are the chances he will get better/what is his prognosis? Is there different treatment that can also help?
